Installation instruction (for reference only)

Installation tips:

(1) The product is installed vertically on the field pressure connection.

(2) During the outdoor installation, try to put the transmitter in a dry and ventilated place, and avoid direct strong sunshine and rain, or else the performance will become poor or break down.

(3) When the product is installed in the area with frequent lightning, “lightning protection” should be indicated when ordering; meanwhile, we suggest that the user additionally install the lightning protection equipment on site, and ensure reliable grounding of the product and the power supply, which can reduce the probability of the transmitter damage caused by the lightning.

(4) If no output or abnormal output of the transmitter is found after the installation, please check:

①　Whether the electrical connection is accurate and firm;

②　Whether the supply voltage is too low and whether the load resistance is too high.
